Title: Method and device for sealing resin-sealed-type semiconductor device
Inventor: MURAYAMA TOSHIHIRO
IPC: H01L21/56
Filed: 1992-05-20
Abstract: PURPOSE:To prevent the deformation of a die pad or the occurrence of voids by letting fused rein flow into a mold, while fixing a die pad inside a mold so that the die-pad may not shift by the fused resin by the fused resin flowing in the mold, thereby sealing a semiconductor chip with resin. CONSTITUTION:When a lead frame, where a semiconductor chip 8 is mounted and fixed on a die pad 2, is placed in the specified position of a bottom force 30A and is fastened with top and bottom forces 20A and 30A, being welded with the top force 20A, opposed die pad fixing pins 25 and 32 press the flat part of each suspension lead 6. When sealing resin is injected from an injection port 31 in this condition, even if a difference occurs in the passages above and below the semiconductor chip 8, wherein resin is flowing, the voids or the deformation of the die pads or the suspension lead 6 can be avoided at sealing with resin since each suspension lead 6 suspending the die pad 2 is fixed. Moreover, the die pad 2 never twists.

Title: Forming method for rugged patterns on woody fiber plate by dry method
Inventor: YUGAWA KIMIO
IPC: B27N5/00
Filed: 1987-05-25
Abstract: PURPOSE:To form desired rugged patterns easily by cutting a surface low gravity layer of a woody fiber plate formed by the dry method, exposing an inner high gravity layer, compressing the same by means of a heat embossing machine immediately after water is sprayed on its surface to make the same in a state of containing high water content. CONSTITUTION:A woody fiber plate manufactured by the dry method is inserted into a sanding device and a high gravity layer constituted of a black rock bed-shaped layer is exposed by cutting the surface low gravity layer. Next, water is sprayed on the surface of the fiber plate by a proper coating device such as a spray, a flow coater, a roll coater or the like to be infiltrated into the high gravity layer exposed to the surface, which turns into a state of containing high water content. In that case, a surface active agent can be added to the water, or water vapor can be sprayed. Then, while in the state of high water containing state, the high gravity layer is compressed by a heat embossing machine to form desired rugged patterns. A black rock bed-shaped layer exposed to the surface by grinding is of extremely dense and hard structure, but as a result of spraying, the same is in the state of high water containing, and the fibers themselves are plasticized, and as the plasticization is further accelerated by the heat at the time of embossing process, the emboss processing can be carried out easily and sharply.

Title: Controller for copying machine
Inventor: NAKAMURA SHINICHI
IPC: G03G21/00
Filed: 1986-06-04
Abstract: PURPOSE:To prevent the breakage of a controller for copying machine owing to an abnormal action by detecting the runaway of a microprocessor which controls the copying machine and switching off a load driving power supply. CONSTITUTION:A CPU 2 of a microprocessor produces pulses through an output terminal 2a in a prescribed cycle at the time of normal action. If a program has runaway, the terminal 2a is fixed at a high or low level. This state is detected by a runaway detecting circuit 3 and a reset signal is supplied to a reset terminal 2b of the CPU 2. Thus the CPU 2 is reset. At the same time, a signal is applied to a remote terminal 5a of a load driving power supply 5 for copying machine via a buffer 4. Then the power supply is switched off. As a result, the load has no actuation regardless of the state of the terminal 2a and therefore a controller for copying machine is never broken down by an abnormal action.
